UNITED STATES JOHN S. SUBBAUGH, OF VINCENNES, INDIANA.

SHOVEL AND SCOO? BLADE.

Application filed June 20, 1923.

To all whom it may concern:

Be it known that I, JOHN S. SURnAUeH, a citizen of the United States, residing at Vincennes, in the county of Knox and State of Indiana, have invented certain new and useful Improvements in Shovel and Scoop Blades, of which the following is a specification, reference being had therein to the accompanying drawing.

The present invention relates to shovel and scoop blades having upstruck rolls or frogs at the rear ends thereof for the re ception and fastening of the handles therein, and the primary object of the invention is to flange the rear edge portion of the blade in order to brace and stiffen the blade and to obtain several other advantages as hereinafter pointed out.

Another object is the provision of such a blade stamped from a single blank of sheet metal, whereby the added advantages and benefits are obtained without adding appreciable weight or expense.

lVith the foregoing and other objects in View, which Will be apparent as the description proceeds, the invention resides in the construction and formation of the blade, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein- Figure 1 is a plan view of one form of blade including the improvement.

Figs. 2 and 3 are sections on the lines 2-2 and 33 of Fig. 1, on an enlarged scale.

Fig. 4 is aplan view of the blank from which the blade is stamped.

Figs. 5, 6 and 7 are plan views showing modifications.

The shovel blade illustrated in Figs. 1, 2 and 3 is stamped or pressed from ablank of suitable sheet metal, as seen in Fig. 4, and comprises the flat body portion or bottom 10, with the inclined or upwardly deflected side walls 11 and the rear inclined or upwardly deflected wall or back 12, such walls being integral with and upturned from the body portion or bottom, and said walls also being integral at their junctures at the rear corners of the blade. This hollow-back type of blade is formed with a longitudinal upstruck roll or frog 13 mid- Serial No. 846,704.

way between the sides and extending from adjacent to the rear end of the blade 01' edge of the back 12 across the juncture or bend between the back 12 and body portion 10, with the forward end of the roll or frog terminating within and merging into the body portion 10 near the center of said body portion. The roll or frog tapers or decreases in width forwardly from its rear end, and braces or reenforces the blades for transmitting the strains between the handle member and blade in an effective manner.

The handle member which extends into and fits within the roll can be secured to the roll or blade in any suitable manner, such as disclosed in my prior patents and copending application, viz., Patent No. 1,247 O32, granted November 20, 1917, Patent No. 1,312,766, granted August 12, 1919, Patent No. 1,374,336, granted April 12, 1921, Patent No. 1,445,185, granted February 13, 1923 and application Serial No. 593,559, filed October 10, 1922.

In carrying out the invention the blade has the integral flanges 14 forming part of the rear edge thereof and located at the opposite sides of the roll 13, and said flanges are struck or bent upwardly at an obtuse or right angle with the back or rear wall 12. The inner or adjacent ends of the flanges 14 are connected or united by an arched yoke flange 15 extending over and upturned from the rear end of the roll 13, thus providing a continuous flange along or constituting the rear edge of the blade and extending from one rear corner of the blade to the other rear corner and over or across the rear end of the roll. The flange 15 is preferably of less height than the flanges 14, and said flanges not only stiffen or reenforce the rear portion of the blade, but also constitute strong braces be tween the roll and back or rear wall 12 of the blade. The rear edge portion of. the blade thus extends upwardly at an angle beyond and across the rear end of the roll, and also extends upwardly at an angle relatively to the crown of the roll beyond the rear end of the roll from one side of the roll to the other. The rear end of the roll terminates in a plane at an angle to the plane of the back Wall 12, and the flanges 14 are located substantially in said plane of the rear end of the roll with their inner ends merging into and united with the sides of the roll at the rear extremity thereof above the plane of the back wall.

The opposite ends of the flanges 1d are curved forwardly and united with the side edges of the blade, thus providing the gussets 16 uniting the opposite Or outer ends of the flanges 1 1 and the rear portions of the edges of the side walls 11, in order to provide strength at the rear corners of the blade, and to brace the flanges 1 1 against forward or rearward bending action.

By having the flanges comprising the rear edge of the blade, the benefits of the improvement are obtained in a most economical manner, inasmuch as the additional stock required is small, thereby not adding appreciably t the weight of the blade, and requiring no securing rivets or elements, in asmuch as the blade is of one single piece, which can be readily formed or fashioned into shape by suitable dies. The flanges being integral with the blade will not be loosened or detached.

The flaiiges will greatly increase the bracing of the blade against torsional strains, and will also materially increase the bracing of the blade against vertical or downward prying strains, such downward prying being the great-est strain to which a shovel or similar implement is subjected, that is, when the blade is pryed forwardly or upwardly by swinging the handle rearwardly or downwardly. The flanges also afford protection to the hand of the user, it

being the customary practice of the user,

in handling coal, crushed rock, etc, to place one hand immediately in rear of the blade, and it not infrequently happens that the material will project beyond the rear edge of the blade so as to bruise or cut the hand. This is especially true in coal mines, where the light is not best, and the coal after being loosened in blasting presents a very ragged appearance, with innumerable projecting points and sharp corners beneath which the operator must thrust his shovel in loading The flanges thus serve as a shield to prevent the material or load on the blade from projecting rearwardly be yond the rear edge of the blade, and, furthermore, the flanges permit the material to pile up at the rear edge of the blade to a much greater extent than is possible with the usual formation of coal shovel blades as made heretofore. In other words, the material on the blade can be piled up at the rear edge of the blade, and the flanges will therefore materially increase the capacity of the implement, as well as obtaining the brae ing action and protection to the hands.

The flanged rear edge of the blade also permits the flai'iges to be used as a foot rest or pry in thrusting the blade into or under the material to be handled, and the flanges provide broad surfaces for the pressure of the shoe or boot, so as not to cut through the sole, and to distribute the pressure 011 the feet. This is an important consideration for the users of shovels used in railroad work, and for spades.

Fig. shows the rear flanges 1d merging into and united with the side walls 11, and having their inner or adjacent ends united with the side walls of the roll 13, omitting the flange over the roll.

Fig. (3 shows the flanges 14" united by the flange extending over the roll, with the flanges 1 1 decreasing in width or tapering to their outer or opposite ends which terminate at the rear corners of the blade without extending forwardly into the side walls 11.

Fig. 7 shows a blade with a rounded rear end, instead of being square, as shown in Figs. 1, 5 and (S. The side walls 11 are upturned from the body portion or bottom 10 and converge rearwardly into the rounded upturned rear wall or back 12. The roll 13 is upstruck from the rear wall 12 and bottom or body portion 10. The upstruck flanges let connect the rear edge of the rear vall or back 12 and side walls of the roll 13 at the opposite sides and rear end of the roll. The flanges 14 may extend to different distances from the roll.

The flanges can also be used on other types of shovel, spade and scoop blades having the upstruck rolls, as will be apparent from the foregoing. The improvement may-also be used on plain back shovels having the handle-receiving rolls atthe rear edges thereof, and the flanges may be at an obtuse angle with the backs or bodies of the blades.

Having thus described the invention, what is claimed as new is 1. A sheet metal implement blade formed from a blank and having an upstruck handle-receiving roll whose rear end terminates at the rear edge portion of the blade at an angle to the body of the blade, said blade having upstanding flanges at the opposite sides of the roll forming portions of the rear edge of the blade and disposed at substantially the same angle to the body of the blade as the rear end of the roll, the adjacent end portions of said flanges merging into and being integral with the sides of the roll above the body of the blade flush with the rear end of the roll.

2. A sheet metal implement blade having an inclined back and an upstruck handlereceiving roll extending forwardly from the rear edge portion of said back to a point forwardly beyond the back, said back haying flanges at the opposite sides of said roll comprising portions of the rear edge of the blade, the rear end of the roll tern'iinating at the rear edge of the back and being arranged at an angle with said back, said flanges being arranged at substantially the same angle with the back and having their adjacent end portions merging into and integral With the sides of the roll above the back and flush with the rear end of the roll.

3. An implement blade having a handlereceiving roll extending from its rear edge, flanges at said edge at the opposite sides of the roll, and a flange uniting said flanges and extending across the roll, said flanges being integral with the roll.

4. An implement blade having an up struck handle-receiving roll extending from its rear edge integral flanges at said rear edge extending upwardly at an angle, and an arched flange connecting said flanges and extending over and upwardly from said roll, said flanges being integral with the rear end of the roll.

5. A sheet metal implement blade having an upstruck handle-receiving roll extending forwardly from near its rear edge, with the rear edge portion of the blade extending upwardly at an angle across the rear end of the roll and at an angle to the crown of the roll.

6. A sheet metal implement blade having an upstruck handle-receiving roll extending forwardly from near its rear edge, and having its rear edge portion extending upwardly at an angle at opposite sides of the roll and across the rear end of the roll with said edge portion extending upwardly at an angle from the crown of the roll.

In testimony whereof I hereunto aflix my signature.

JOHN S. SURBAUGH.
